Wireguard VPN stopped working correctly after recent S25 software update

After a recent update (S931BXXU3AYE7 from 2025-06-02) the VPN connection via Wireguard to my home network stopped working. Theoretically the connection seems established and neither side of the tunnel is reporting an issue, but the devices on the home network are no longer accessible from the phone. Nothing else in the setup changed except from the software update of my Galaxy S25 . There was one update after that but it didn't change anything.

Is this a known issue? Is a fix coming? Or perhaps someone has a workaround?

Did you check and restart home setup

Yes, I tried:

• restarting the router
• restarting the phone
• generating new keys and reconfiguring the VPN tunnel
• reinstalling wireguard app on the phone

Nothing seems to help. At the same my time my son's setup on a Galaxy S23 works without issues.

Absolutely the same issue here. S25 an S21. 

It seems to be connected to a CG NAT lite Internet home connection
